Earlier on Wednesday, Xie - who maintains his innocence - became emotional as a friend of Henry Lin described how the 12-year-old talked about his "uncle Robert" constantly on the internet chat program MSN.

"He talked about his uncle Robert a lot and talked in terms of respecting Robert's badminton ability ... and wanted to practise with uncle Robert as much as he would allow him?" Xie's barrister Graham Turnbull SC asked her.
